Sometimes there are moments when everything in your life goes wrong, and when you feel very bad. In such times meditation will not help. The solution is having the courage to take whatever comes and willingly confronting the unknown again and again.
The “three fierce mantras” come from a 12th-century Tibetan master. They express, very concisely, an undaunted spirit willing to face any challenge or hardship. Repeating them to yourself may give you some courage in trying times.
Practice the three fierce mantras.
